Your Ash trees can be treated if management begins before they are infested. Once the EAB larvae have killed more than 30 percent of the canopy it is fatal. Now that EAB has been in Omaha, we’re recommending all untreated Ash trees to be Trunk Injected with a product that contains emamectin benzoate. This product has been found to be 99% effective at stopping Emerald Ash Borers cycle, and usually lasts for a little over 2 years. On the third year of the treatment cycle we will perform a Soil Injection into the root system in the Fall as a “Booster Shot” which lasts until the next year’s Trunk Injection. Our method helps minimize the possible scarring of the trunk injections every two years and allows us time to get the treatment to the Ash tree at the optimal time. Our goal is to maintain a high concentration of product in the system of the tree. This procedure is only effective if we continue the series of treatments for the life of the Ash Tree.
